摘要
人们对电动自行车的行车便捷性及轻便性的要求越来越高,市场需求量逐渐增加,电动自行车的轻量化已成为目前研究的热点之一。为实现某电动自行车车架的轻量化,同时提升车架结构强度,本研究用高强钢材料代替普通钢材,建立电动自行车整车车架/前叉组合件三维几何模型,并对该模型进行静力学有限元仿真,分析车架/前叉组合件的应力及应变云图,识别车架的应力集中及应变量较大的位置,并对其位置进行结构优化,从而实现车架轻量化,整车减重10%。
The market demand for electric bicycles has gradually increased due to traffic convenience,and to achieve lightweight electric bicycles has been becoming an urgent task for major electric bicycle manufacturers.In order to achieve the lightweight of an electric bicycle frame and improve the structural strength,high-strength steel materials are employed to replace ordinary steel.By establishing a three-dimensional model of the complete electric bicycle frame/front fork assembly and then performing static finite element simulation on the model,the stress and strain nephogram of the frame/front fork assembly is analyzed.Based on these results,the stress concentration and large strain position of the frame are identified,and the position is optimized.Eventually,the weight of the whole vehicle is reduced by 10%.
